javascript - Grunt: Task "grunt-bower" not found -


i want install package grunt-bower grunt using npm install grunt-bower --save. after install, see package grunt-bower inside node_modules. here gruntfile.js:

module.exports = function(grunt) {     grunt.initconfig({          bower: {             dev: {                 dest: 'public',                 js_dest: 'public/javascripts',                 css_dest: 'public/stylesheets'             }         },          watch: {             source: {                 files: ['sass/**/*.scss', 'views/**/*.jade'],                 tasks: ['sass'],                 options: {                     livereload: true, // needed run livereload                 }             }         }     });      grunt.loadnpmtasks('grunt-bower');     grunt.loadnpmtasks('grunt-contrib-watch');      grunt.registertask('default', ['grunt-bower']);  };

i have register on official page : grunt.loadnpmtasks('grunt-bower'); when run grunt command, meet error:

warning: task "grunt-bower" not found. use --force continue.

i don't know why. wrong ? please tell me.

thanks :)

you've defined task want run bower , not grunt-bower therefore,

grunt.registertask('default', ['grunt-bower']);

should be

grunt.registertask('default', ['bower']);
